Seu is a Planter and serves as Mensab's protector. Known for his prowess with a sword and unwavering loyalty, Seu acts as a formidable bodyguard. Whenever he suffers severe injuries, Mensab takes him to be healed by advanced equipment capable of repairing any damage and synthesizing any substance. However, each time Seu undergoes this process, he loses some of his memories.
Following the silicon creature invasion, only Mensab's people survived, but they were likely killed during the destruction of Toha Heavy Industries. This makes Seu potentially the last living Planter. Eventually, Seu retreats with Mensab and the recorded personalities of other Planters into a time-space rift to ensure their safety. Unfortunately, due to the technological stagnation in The City and the destruction of Toha, they are trapped within this rift indefinitely.
